Credit Card Interest Calculator

This credit card interest calculator figures how much of your monthly payment is applied to principal and how much is interest. It then tells you how many months until the card is paid off (assuming no additional charges) and your total interest cost until payoff.

How Much Credit Card Interest Will You Pay?

What if you could know exactly how much interest you’re paying, and when you’ll get to say goodbye to your credit card debt?

Thankfully, our Credit Card Interest Calculator will transform these uncertainties into knowledge you can use to formulate your debt reduction strategy.

How Much Interest Will You Pay?

The amount of interest you pay is calculated based on your annual interest rate, balance, and how much you pay each month. Fortunately, this Credit Card Interest Calculator makes the math easy. Simply input the variables, click the “Calculate Credit Card Interest” button, and you’ll learn not only the total amount of interest you’ll pay, but also:

The amount of your next payment that will be applied to principal

The amount of your next payment that will be applied to interest

The number of monthly payments until your balance reaches zero

The number of years until your balance reaches zero

In addition, you can lower the overall amount of interest you’ll pay by negotiating a lower interest rate or increasing your payments. The more creative you get, the less you’ll pay!

How Credit Card Interest Works

Although credit card interest rates are set annually, they will charge you interest daily and bill you monthly. Credit card companies calculate interest based on your average daily balance. That means that if you are not paying your credit card balance in full, you will not only pay interest on purchases but also on the interest itself!

The average daily balance method is used to level out the day-to-day fluctuations caused by payments and purchases making it easier to calculate interest. The average daily interest rate is usually shown on billing statements but few customers understand the implications. Most people just see the aggregate finance charge on their bill and have no idea that it represents a cumulative tally of each day’s interest charges for the entire month.

How To Avoid Credit Card Interest

Smart consumers don’t waste their money on credit card interest and employ a variety of strategies to minimize charges.

The ideal strategy is to pay your bill in full before the due date so you don’t get charged interest. But if you take cash out of an ATM with your credit card, or pay anything less than the full amount on your statement, you will incur finance charges.

Credit card companies offer a specified number of interest-free days (often 44 to 55 days) as a grace period to give you time to pay your bill without interest. However, as soon as you let a balance carry over to another billing cycle then you’ll lose the grace period privilege and have to earn it back by paying your balance in full during two successive months.

Cash advances are usually excluded from the grace period rule. In other words, there are no interest-free days for cash advances, and there’s usually a service fee to pay as well. Interest on cash

advances is charged immediately from the day the money is withdrawn.

The best strategy is to avoid cash advances and pay your credit card bills in full every month.

Remember: Credit cards are convenient tools that can be used to your advantage, but you must be careful and stay out of debt. Only buy what you can afford to pay for immediately.
